Fixed #538, #880 and #586. This one is a more robust solution than #884 or #894. Can be activated via `SDWebImageScaleDownLargeImages` or `SDWebImageDownloaderScaleDownLargeImages` #### Fixes - Fixed #1668 CGContextDrawImage: invalid context 0x0 - b366d84 ## [4.0.0 beta - New platforms (Mac OS X and watchOS) + refactoring, on Oct 5th, 2016](https://github.com/rs/SDWebImage/releases/tag/4.0.0-beta) See [all tickets marked for the 4.0.0 release](https://github.com/rs/SDWebImage/milestone/3) #### Infrastructure: - support for **watchOS** and **OS X** platforms #1595 - the `SDWebImage xcodeproj` contains the following targets: - `SDWebImage iOS static` (iOS static lib) - `SDWebImage watchOS static` (watchOS static lib) - `SDWebImage OSX` (OSX dynamic framework) - `SDWebImage iOS` (iOS dynamic framework) - `SDWebImage tvOS` (tvOS dynamic framework) - `SDWebImage watchOS` (watchOS dynamic framework) - the `SDWebImage Demo xcodeproj` contains the following targets: - `SDWebImage OSX Demo` - `SDWebImage iOS Demo` - `SDWebImage TV Demo` - `SDWebImage Watch Demo` - bumped `libwep` version to `0.5.1` - improved unit testing code coverage (*35%* -> **77%**) and integrated [CodeCov](https://codecov.io/gh/rs/SDWebImage) #### Backwards incompatible changes - removed all deprecated methods (that we carried around for backwards compatibility in previous versions) #774 - Renamed `SDWebImageManager` `downloadImageWithURL:options:progress:completed:` to `loadImageWithURL:options:progress:completed:` as it makes more sense, since we check the cache first and download only if needed a32a177 - Deleted targets: `SDWebImage+MKAnnotation`, `SDWebImage+WebP`, `SDWebImageFramework`: - `SDWebImage `target that build as a static library (all subspecs included) -> `libSDWebImage.a` - `SDWebImageiOS` and `SDWebImagetvOS` targets that build as dynamic frameworks - Renamed the dynamic frameworks targets from `WebImage` to `SDWebImage`. Renamed the `WebImage.h` to `SDWebImage.h` to match the framework naming - Renamed the schemes for consistency. Updated the Tests Podfile + project. - For #883 Fix multiple requests for same image and then canceling one, several breaking changes were needed: - `SDWebImageDownloader` method `- downloadImageWithURL:options:progress:completed:` now returns a `SDWebImageDownloadToken *` instead of `id ` (give the ability to cancel downloads using the returned token) - `SDWebImageDownloaderOperation` initializer `- initWithRequest:options:progress:completed:cancelled` split into `- initWithRequest:options` and `addHandlersForProgress:completed:`. Note: there is no more cancel block - Modern Objective-C syntax done in 64382b9 includes: - initializers now return `instancetype` instead of `id` - explicit designated initializers (i.e. for `SDImageCache`) - For #1575 GIF support using FLAnimatedImage, several changes were needed: - replaced type `SDWebImageQueryCompletedBlock` with `SDCacheQueryCompletedBlock` and added an `NSData *` param - because of the change above, the `done` param of `SDImageCache` `queryDiskCacheForKey:done:` is now a `SDCacheQueryCompletedBlock` and those blocks must now include an `NSData *` param - replaced type `SDWebImageCompletionWithFinishedBlock` with `SDInternalCompletionBlock` and added an `NSData *` param - because of the change above, the `completed` param of `SDWebImageManager` `loadImageWithURL:options:progress:completed:` is now `SDInternalCompletionBlock` and those blocks must now include an `NSData *` param - for consistency with the previous change, also renamed `SDWebImageCompletionBlock` to `SDExternalCompletionBlock` - `UIImage` will no longer respond to `sd_animatedGIFNamed:` or `sd_animatedImageByScalingAndCroppingToSize:` - Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581 - breaks compatibility at least for Swift users of the framework - **watchOS** and **OS X** support #1595 required - renamed `SDWebImage` iOS static lib target to `SDWebImage iOS static` for clarity - improving the unit tests code coverage #1681 required - Refactored `NSData` `ImageContentType` category, instead of returning the contentType as a string, the new added method `sd_imageFormatForImageData` will return a `SDImageFormat` enum value - `SDImageCache` configuration properties moved into `SDImageCacheConfig` (which is now available via `config` property): - `shouldDecompressImages` - `shouldDisableiCloud` - `shouldCacheImagesInMemory` - `maxCacheAge` - `maxCacheSize` - The `storeImage:` methods from `SDImageCache` were async already, but declared as sync. Properly marked them as async + added completion. Got rid of the recalculate param. If the `NSData` is provided, use it. Otherwise, recalculate from the `UIImage` - Removed the synchronous methods `diskImageExistsForURL:` and `cachedImageExistsForURL:` from `SDWebImageManager` - Removed the synchronous method `diskImageExistsWithKey:` from `SDImageCache` - Get rid of the confusion caused by `cleanDisk` and `clearDisk` on `SDImageCache`. Renamed `cleanDisk` to `deleteOldFiles`. No longer expose the sync `clearDisk` and `deleteOldFiles`, just the async ones. - Renamed `SDImageCache` `queryDiskCacheForKey:done:` to `queryCacheOperationForKey:done:` - Another `SDImageCache` clarification: `imageFromDiskCacheForKey:` used to also check the memory cache which I think is misleading. Now `imageFromDiskCacheForKey` only checks the disk cache and the new method `imageFromCacheForKey` checks both caches - Got rid of `removeImageForKey:` and `removeImageForKey:fromDisk:` from `SDImageCache` that looked sync but were async. Left only the 2 async ones - Removed `UIImageView` `sd_cancelCurrentHighlightedImageLoad` - Added `sd_` prefix to the activity indicator related methods (`setShowActivityIndicatorView:`, `setIndicatorStyle:`, `showActivityIndicatorView`, `addActivityIndicator`, `removeActivityIndicator`) #1640 - Use `dispatch_main_async_safe` for all the completion blocks on the main queue (used to be `dispatch_sync`) - avoiding locks. - Removed `dispatch_main_sync_safe` as it can be mistakenly used - Add `url` as param to progress block `SDWebImageDownloaderProgressBlock` - #984 #### Features: - Switched our GIF support to a better implementation: [FLAnimatedImage by Flipboard](https://github.com/Flipboard/FLAnimatedImage) #1575 - requires iOS 8+ (it's the only way due to FLAnimatedImage requirements) - the implementation relies on a `WebCache` category on top of `FLAnimatedImageView` - details in the [README](README.md#animated-images-gif-support) - Converted any remaining code to Modern Objective-C syntax - 64382b9 - Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581 - via #1595 Clarified and simplified the usage of `TARGET_OS_*` macros. Added `SD_MAC`, `SD_UIKIT`, `SD_IOS`, `SD_TV`, `SD_WATCH`. The biggest issue here was `TARGET_OS_MAC` was 1 for all platforms and we couldn't rely on it. - Replaces #1398 Allow to customise cache and image downloader instances used with `SDWebImageManager` - added a new initializer (`initWithCache:downloader:`) 9112170 - `UIImage` responds to `sd_imageData` and `sd_imageDataAsFormat:` via the `MultiFormat` category. Those methods transform a `UIImage` to the `NSData` representation 82d1f2e - Created `SDWebImageDownloaderOperationInterface` to describe the behavior of a downloader operation. Any custom operation must conform to this protocol df3b6a5 - Refactored all the duplicate code from our `WebCache` categories into a `UIView` `WebCache` category. All the other categories will make calls to this one. Customization of setting the image is done via the `setImageBlock` and the `operationKey` e1840c3 - Due to the change above, the activity indicator can now be added to `UIButton`, `MKAnnotationView`, `UIImageView` - Animated WebP support #1438 - The shared objects (not really singletons) should allow subclassing, therefore the return type of the shared resource method should be `instancetype` and not a fixed type - c57cf7e - Allow to specify `NSURLSessionConfiguration` for `SDWebImageDownloader` #1654 - Add `url` as param to progress block `SDWebImageDownloaderProgressBlock` - #984 #### Fixes: - Fix multiple requests for same image and then canceling one #883 + 8a78586 - Fixed #1444 and the master build thanks to [@kenmaz](https://github.com/kenmaz/SDWebImage/commit/5034c334be50765dfe4e97c48bcb74ef64175188) - Fixed an issue with the `SDWebImageDownloaderOperation` : `cancelInternal` was not called because of the old mechanism rellying on the `thread` property - probably because that thread did not have a runloop. Removed that and now cancelInternal is called as expected f4bdae6 - Replaced #781 on replacing dispatch_sync with dispatch_async for the main queue 062e50a f7e8246 c77adf4 fdb8b2c 265ace4 0c47bc3. Check for main queue instead of main thread. - Fixed #1619 iOS 10 crash (`setObjectForKey: object cannot be nil`) - #1676 7940577 - Fixed #1326 #1424 (`Carthage bitcode issue`) - #1593 - Fixed #1639 via #1657 (`Add support for downloading images behind redirect`) - Replaced #1537 via 9cd6779 - fixed a potential retain cycle - Updated `dispatch_main_async_safe` macro in order to avoid redefinition when included as Pod - Fixed #1089 by updating the docs on the calling queue for the `progressBlock` (background queue) - Fixed a compilation issue on `FLAnimatedImageView+WebCache` - #1687 ## [3.8.2 Patch release for 3.8.0 on Sep 5th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.8.2) #### Fixes: - Fixed #1608 #1623 #1644 Crash in `[NSURLCache cachedResponseForRequest:]` - the fix is actually avoiding to access `NSURLCache` which appears to generate a race condition. We only call it if necesarry (`SDWebImageRefreshCached` is used and the image cannot be cached by the system when it's too big or behind authentication) ## [3.8.1 Patch release for 3.8.0 on Jun 7th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.8.1) #### Fixes: - SDWebImage 3.8.0 get wrong image #1589 - the issue was caused by the changes in 3.8.0 (Removed the URL query params from the filename (key) fb0cdb6d 1bf62d4 #1584 - fixes #1433 #1553 #1583 #1585) - Reverted. - Note: The solution for those issues (i.e. #1433 #1553) is to set the `SDWebImageManager` `cacheKeyFilter` block and do their own calculations there. ## [3.8.0 Minor release - Replaces NSURLConnection (deprecated) with NSURLSession - on Jun 6th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.8.0) #### Infrastructure: - Had to update the iOS deployment target to 7.0 from 5 - 6545a3a #### Features: - Replace deprecated `NSURLConnection` with `NSURLSession` #1578 #1586 - fixes #1291 #1318 #823 #1566 #1515 - Allow to customise cache and image downloader instances used with `SDWebImageManager` 86fc47bf7b - fixes #1398 #870 #### Fixes: - Removed the URL query params from the filename (key) fb0cdb6d 1bf62d4 #1584 - fixes #1433 #1553 #1583 #1585 - Fixed the WebP build with the official 1.0.0 CocoaPods release f1a471e - fixes #1444 - Updated doc: `removeImageForKey:` not synchronous e6e5c51 - fixes #1379 #1415 ## [3.7.6 Patch release for 3.7.0 on May 8th, 2016](https://github.com/rs/SDWebImage/releases/tag/3.7.6) #### Infrastructure: - Changed the **libwebp git url** so that people from China can access it - #1390 (from `https://chromium.googlesource.com/webm/libwebp` to `https://github.com/webmproject/libwebp`) #### Features: - Added `cancelAllDownloads` method to `SDWebImageDownloader` #1504 - Added API to save image `NSData` to disk cache: `[SDImageCache storeImageDataToDisk:forKey:]` #1453 #### Fixes: - Fix #1449: Version 3.7.5 breaks semantic versioning (removes public API).
